Preparing for possible disruptions is an important (yet overlooked) part of building a successful business. Backup and disaster recovery are essential for business continuity. Data breaches, power outages, and other events can cause permanent data loss and reputation damage, as well as revenue loss. This article provides an introduction to disaster recovery and backup (BDR). Both are related practices which help businesses to respond and overcome unfortunate incidents. We outline what your company stands to get from BDR and provide all the resources you need to start developing an effective business continuity strategy.
What are Backup and Disaster Recovery?
A backup is a copy of data you can use to restore a file if something happens to the original. Creating a data backup protects against most incidents that jeopardize data integrity and safety, such as:
Accidental deletion or failure to save progress.
Losing a device with a valuable file.
A software bug.
- An infrastructure or service-based issue.
- Data theft (either by an external or insider actor).
- Database corruption.
- Faulty patching.
- A crashed hard drive.
- On the other hand, disaster recovery is a step-by-step plan for quickly regaining the use of apps and IT resources after an incident. Companies create a DR plan for two types of incidents:
- Natural disasters that cause physical damage and disrupt power grids (earthquakes, tornadoes, floods, wildfires, tsunamis, etc.
Natural disasters that cause physical damage and disrupt power grids (earthquakes, tornadoes, floods, wildfires, tsunamis, etc.). or unintentional (accidental explosion, system failure, app bug, etc. A DR plan usually requires a backup set of servers or storage systems that can be used if the primary IT setup is destroyed by someone or something. Most DR plans rely upon some form of backup. Backups are not sufficient to guarantee business continuity. Only a robust DR strategy can guarantee your company can continue operating in case of a disaster.
- Why Do We Need Backup and Disaster Recovery?Let us look at the main reasons businesses of all sizes decide to invest in backup and disaster recovery.
- The Cost of Downtime is Too GreatDowntime happens when apps and data become unavailable to end-users (e.g., because of a natural disaster or DDoS attack). When you suffer downtime, the effects echo throughout the entire company:
Employees cannot do their jobs.
- Transactions do not go through.
- Customers turn to competitors.
- Business revenue comes to a halt.
Here are some facts and numbers that clearly show the importance of avoiding downtime:
Around 66% of companies report that unplanned downtime hinders their digital transformation.
For a small business, the per-event cost of downtime sits between $82,000 and $256,000.
The cost of IT network downtime currently averages at $300,000 per hour ($5,600 per minute).
- The average price of downtime is becoming more expensive each year by 36%.
- Disaster recovery planning is the recipe for preventing high amounts of unplanned downtime. You can avoid downtime by switching to secondary IT resources during a disaster. Our article on data center tiers compares different facility types and shows what they offer in terms of uptime guarantees.
- Avoiding Permanent Data Loss
- If someone or something deletes a file that has no backup, that data is gone forever. Unfortunately, there are many ways you can lose a piece of data, such as:
Accidental or malicious deletion.
- Hardware failure.
- Cyberattack.
- Data corruption.
- Physical damage to a storage unit.
A proper data backup enables you to return the file to the last known good point in time before the problem. The strategy does not protect data from theft but guarantees that you never lose a valuable file permanently.
Damage Control in Times of Crisis
Unfortunate events always cause damage, but backup and disaster recovery enable a company to control the extent of the damage. Here are a few examples:
If you fire someone and the angry employee decides to delete files out of spite, a backup enables you to restore any data deleted by the ex-worker.
- A backup failover site in a different region can keep you operational if the primary data center is in the midst of a region-wide power outage.
- If you lose some of your infrastructure in a fire, you can restore all data on lost devices from a cloud backup.
- A DR plan to move all equipment off the floor and into a windowless room can save the entire IT setup in a hurricane scenario.
- When an intruder makes their way into your network, a disaster recovery plan ensures a swift response that limits lateral movement and controls the blast radius.
- If you suffer a ransomware attack, a proper DR plan helps stop the attacker from spreading to new devices, while backups ensure you can restore encrypted data.

Protecting Your Brand’s Reputation
Being known as a company that lost customer data in the past does no favors to your business. Once you lose the trust of current customers, they start to discourage others from using or working for your company.
- Unhappy users also leave negative comments about your business online, giving poor ratings that can hinder customer acquisition for years. Cyber threats are a matter of when, not if.
- While it’s important to take a proactive cybersecurity approach with robust firewalls, and intrusion detection system, you shouldn’t assume that your business is secure. It is just as important to prepare a plan of action for a successful attack as it is to implement prevention measures.
- Proper DR planning ensures the team knows how to:
- Quickly identify different types of threats.
- Respond promptly and correctly to each threat type.
- Follow through on the process of removing the attacker from the network.
On the other hand, backups mitigate data loss and ensure you can recover from an attack without long-term problems.
Protecting Your Remote Workforce
While remote work and BYOD have a range of benefits, these strategies also have certain risks:
The business has limited visibility into how an employee uses and protects the device.
A personal device typically has weak security and easy-to-crack passwords.
Out-of-office work means more chances for someone to steal or lose a device with access to sensitive data.
A home network is typically far less secure than its corporate counterpart.
- An employee also uses a BYOD device for personal reasons, creating a broader attack surface.
- Remote work and BYOD devices can easily lead to permanent data loss without a proper backup. A DR plan will ensure that the security team can quickly disable a lost device, or wipe data in order to prevent outsiders from accessing company information.
- Lowering the Human Error Factor
Everyone makes mistakes, and your workforce is no different. A continuous backup system will ensure that your employees do not lose data accidentally. Employees often forget to save changes or type incorrect dates. They also delete files accidentally and accidentally press the wrong buttons. Likewise, a DR plan lowers the chance of costly mistakes during the crucial phases of discovering and responding to a threat.
You Need to Stay Compliant
Some companies must have an always-on infrastructure to comply with government regulations, while others need regular data backups to comply with local laws. In those cases, the lack of backup and disaster recovery plans can lead to severe penalties and legal expenses.
- Remember that a business does not get an exception for regulations such as HIPAA and PCI when disaster strikes. Even when things are chaotic, you must maintain compliance. You can ease compliance by using backup and DR. Data backups will ensure that you don’t lose sensitive data in the event of a data breach or leakage. This is required by most data regulations. It is important to keep up-to-date with the latest threats by constantly reviewing your IT systems. Regular reviews mean the team has more chances to spot failures to comply.
- When choosing a provider, always look for a vendor with third-party compliance certifications (such as HIPAA, PCI-DSS, GLBA, and SSAE 18).
- How Does Backup Differentiate from Disaster Recovery?
- Backup and disaster recovery typically work in tandem, but the two are separate practices. The table below offers a high-end comparison of the two strategies:

| Pricing | Even the best backup options are affordable | Expensive as you need to secure access to a secondary set of IT resources (unless you opt for Disaster-Recovery-as-a-Service) |
|---|---|---|
| The two practices are not mutually exclusive. In fact, one without the other will often result in a failure of both. | What to Look After When Choosing a Backup and DR Provider? | Successful backup and disaster recovery start with making the right vendor choice. Unfortunately, there is no one-size-fits-all provider–while some companies find mega-cloud vendors to be an ideal choice, others benefit the most from a smaller provider with affordable managed services. |
| Below are five tips that will help you identify a worthwhile partner: | Find the right backup offering(s): | What are you trying to back up? What are you trying to back up? What backup frequency is required (daily, hourly, when someone makes a change, etc. )? Ensure every vendor you consider supports the unique backup needs of your team. |
| Consider storage locations: | You should not store data backups in areas where a disaster can affect both you and the off-site backup storage. You also do not want backups too far away from the primary data center as great distances can lead to latency issues. | Closely inspect each candidate: |
| Only consider providers with a proven track record of quality service. Look for customer references and, if possible, talk directly to current clients to learn more about the vendor’s operations. | Take compliance into consideration: | Most vendors are compliant with standard privacy and security protections like CCPA and GDPR. However, if you must adhere to some other mandate that involves backups, find a vendor that can help meet those requirements. |
| Look for transparent pricing: | Some vendors needlessly complicate fee calculation (storage costs, ingress, egress, deletion, retrieval and query fees, various pay-as-you-go models, etc.). Look for a partner that provides a transparent, predictable monthly cost. | Disaster-recovery-as-a-service enables you to rely on a cloud-based infrastructure you can switch IT operations to in times of crisis. It is a great alternative to an in-house disaster recovery system for companies that want to be resilient to disasters but don’t have the budget to invest in a second IT setup. Backup and disaster recovery ensure these events do not have long-term business consequences, so putting these strategies in place should be a priority for any careful organization. |
